NTRODUCTION
The CT89 is a precision instrument used to monitor and record temperature on a 6”
circular paper chart. The CT89 may be carried as a portable instrument or mounted
in a fixed location.
The CT89 offers a variety of features to meet any temperature recording require-
ments. A combination of three temperature ranges and four chart speeds provide
a high degree of flexibility. In addition, the chart rotation may be set for single or
continuous turn operation as required by a particular application. To protect the data
being recorded the CT89 uses an automatic battery backup to maintain operation
during a power outage.

CT89 FEATURES AND CONTROLS
1. The 3 DIGIT TEMPERATURE DISPLAY shows temperature of the environment
being monitored. When the batteries are nearly discharged, the display will
alternate the display reading and “LO” to advise the operator that the batteries are
discharged and the CT89 will shortly cease operation.
NOTE: The battery backup feature of the CT89 is primarily intended for use in
situations where primary power is lost for short periods of up to 48 hours. The
CT89 is not intended to be used as a battery powered instrument. If the CT89 is to
be stored for an extended period, it is strongly advised to disconnect the battery
pack and remove the batteries to avoid damage to the instrument from battery
leakage.
2. The TEMPERATURE RANGE SELECTOR allows the user to choose the desired
temperature range for measurement and recording.
3. The CHART SPEED SELECTOR allows the user to select the time of one full
chart revolution. The corresponding chart has to be chosen according to the
desired chart speed. Chart part numbers are listed in this manual.
4. The PEN POSITION ADJUSTMENT KNOB allows the user to adjust the position
of the chart pen.
5. The CHART ADVANCE BUTTON allows the operator to set the chart to the cor-
rect time. Press and hold the chart advance button until the desired time lines
up with the Time Pointer. The chart is rotated counterclockwise only. CAUTION:
Movement of the Chart Spindle (Item 9) by hand may cause permanent dam-
age to the chart mechanism.
5a. The TIME POINTER
6. TEMPERATURE ADJUSTMENT feature allows the user to adjust the reading of
the digital display during periodic calibration. The CT89 has been factory calibrat-
ed and requires no adjustment to meet all published specifications.
7. The POWER ON/OFF / CONTINUOUS / SINGLE CHART SELECTOR allows the
user to apply power to the CT89 and to select Continuous or Single Turn for the
chart rotation. When power is first applied to the CT89, the display will show “888”
to test each segment of the display, and the pen will move to the edge of the
chart. The pen will then move to the correct position on the chart. In the Continu-
ous switch position, the chart will rotate until power is removed. In the Single Turn
switch position, the chart will make one complete revolution and stop. A blinking
dot on the display (Item 1) will indicate that the chart has made one complete
revolution and stopped. To reset the chart for another revolution place the
switch in the Continuous switch position until the blinking dot goes out and then
slide the switch back to the Single Turn position. The chart will make one com-
plete revolution and stop.
DO NOT move the pen by hand or interrupt the pen movement. Failure to observe
this will cause the pen to read incorrectly and may result in damage to the pen
mechanism.
8. The RECORDING PEN contains special ink. The pen has a wrap-around arm
latch which makes the pen replacement “A SNAP!” To replace the pen, gently lift
up the PEN ARM, (do not over bend pen arm) release the pen latch by pushing it

down, and remove the pen; place a new pen on top of the pen arm, align the
notches on the pen arm with the notches on the pen latch and close the latch
by wrapping it around the pen holder until it is secured. Replace cap on the
pen tip when the CT89 is not used to insure long pen life. For pen installation see
Fig. 1.
9. The CHART SPINDLE holds and rotates the chart during the recording opera-
tion. DO NOT ROTATE THE SPINDLE BY HAND AS IT MAY DAMAGE THE
INTERNAL MECHANISM.
10. The PAPER CHART is 6 inches in diameter. in a box of 60 charts each. The
chart part numbers are listed on the following page.
TO INSTALL A NEW CHART disconnect power from the CT89 by selecting
OFF with the Power / Single/ Continuous Chart Selector. Place pen cap on pen
point. Gently lift the pen arm and while holding it remove the old chart. Slide a
new chart under the pen holder and the chart holding tabs. Align the chart with
the chart spindle. Apply power to the CT89 and rotate the chart by depressing
the chart advance button until the time pointer is aligned with the line on the
chart representing the right time or day. Remove the pen cap. If desired, adjust
the pen position according to the scale you wish to record.
11. The ROTATION POINTER indicates direction of chart rotation.
12. The HANDLE for carrying folds towards the back of the case to be out of the
way when CT89 is mounted on the panel or on the wall.
13. The KEYHOLE SLOTS located on the back of the case are provided for wall or
panel mounting.
14. The FRONT COMPARTMENT under chart was designed to store the battery
holder for battery backup as well as the connection for the adapter box.
15. The REMOTE TEMPERATURE SENSOR is interchangeable. The furnished
4" stainless steel sensor has 15 feet of cable. The temperature sensor is an
electronic digital proprietary design for precision and very high interference im-
munity. It utilizes the standard RCA connector.
Note:
The 4 inch metal probe tip may be immersed in fluids compatible with 304
stanless steel. The black platic probe sheathing is moisture resistant, but
should not be submersed. If moisture is present the sheathing should be
protected or probe failure will occur.

16. The BATTERY HOLDER is stored in the front compartment for backup batteries.
Use of 8 alkaline “AA” batteries is required for proper operation.
17. The 12VDC PLUG IN WALL ADAPTER provides primary power for the CT89.
Alternate sources of 12 Volt power may also be used. This allows use of the CT89
in automotive, marine or other mobile applications.
18. The POWER CONNECTOR is a connection point for the 12VDC wall adapter or
alternate source of 12VDC power.
19. Back Brace for counter top use.
